Slack’s features

Slack’s channel feature is its bread and butter — and a staple among Finder employees both in Canada and across the globe. Share threads across internal teams and external clients with integrated file sharing:

  • Dedicated channels. Organize channels by project, team or topic and loop team members into the conversation for updates in real-time from everyone in the channel.
  • Privacy settings. Pivot confidential conversations into private channels with invited team members.
  • Direct messaging. Chat one-on-one with single team members through direct messaging.
  • Searchable history. Scroll up through a channel to see what’s been shared or search by keyword across direct messages and company-wide channels.
  • Video calls. Share your screen and chat face to face with video conferences for up to 15 team members.
  • Automated procedures. Expedite work tasks with Slack workflows — automated actions that include daily reminders, status updates and help requests.

How does Slack work?

Slack is a messaging application that helps teams build collaborative online workspaces. Slack channels help organize company-wide communications into sub-categories, while direct messaging allows for more intimate one-on-ones. The app can be used for both in-person and remote work.

Slack’s offerings can be overwhelming for beginners, but the platform is designed to scale based on the role and responsibilities of each team member. Subcontractors and part-timers may only be looped into a few channels, while supervisors and team leaders may have their finger on the pulse of 10 or more threads.

Jon Brodsky, CEO of Finder US says, “Slack has enabled our crew, which is 70% remote, to collaborate in real-time for several years. It’s easy to share ideas and files, and the fact that conversations happen instantly means that our largely remote workforce is always connected to one another.”

How to set up your employees to work remotely

What I think about Slack

I’ve used Slack as a member of the Finder team for nearly 3 years, both as a part-time freelancer and a full-time staff member. Personally, I’m a big fan. I can pop onto Slack to check in with my manager, see what other teams are up to and share what I’m working on for real-time feedback.

And if I’m in the writing groove and don’t want to be disturbed, I can pause notifications until I’m ready to tackle them, enabling me to work undisturbed and catch up when I’m ready.

Pros and cons


  • App integration. Slack integrates with 2,000 apps across a variety of categories and industries, including data analytics, developer tools, project management, marketing, sales and finance.
  • Monthly billing. No contract is required and you can terminate your service with no cancellation fee.
  • Free service tier. Slack’s basic offerings — the messaging platform, video conferencing and app integrations — are available for free.
  • Learning database. Slack’s comprehensive learning library includes articles that can help you navigate both beginner and advanced platform features.


  • Expensive. Slack’s more sophisticated features come at a cost — its monthly membership fees are higher than many of its competitors, including Flock and Mattermost.
  • No phone support. Tech support is limited to 24-hour email inquiries and live chat support for Standard plans and up from 2 a.m. to 9:30 p.m., Monday to Thursday and 2 a.m. to 5 p.m., on Fridays, Pacific Time (PT).

Customer reviews and complaints

Overall, Slack receives high marks from its customers. With only 2 complaints in the last 3 years, its Better Business Bureau (BBB) page isn’t much to go on. But on Trustpilot, Slack boasts a TrustScore of 4.5 out of 5 based on 93 reviews.

Among the high notes are Slack’s many app integrations, screen sharing and search features, while a handful of customers complained that the software is difficult to pick up for fresh hires.

How do I contact Slack support?

Reaching Slack support is limited to:

  • Email. Fill out a support ticket on Slack’s website for a response for the team usually within the hour.

Bottom line

Slack helps in-person and remote work forces organize communications with dedicated channels, one-to-one direct messaging and a generous sweep of app integrations. But it’s pricier than many of its counterparts and may be challenging for newcomers to master.

Compare other software options to help your business run smoothly.
